To the lay public, Stewart may be best known for a quotation, or a fragment thereof, from his opinion in the obscenity case involving Louis Malle's 1958 film The Lovers. Stewart wrote in his short concurrence that "hard-core pornography" was hard to define, but that "I know it when I see it." Usually dropped from the quote is the remainder of that sentence, "and the motion picture involved in this case is not that." He later recanted this view in Miller v. California, in which he accepted that his prior view was simply untenable.
